지난 1세기동안 전세계적으로 평균수명(출생시의 평균여명)이 약 30년 정도 연장되어 1999년 현재 60세 이상의 고령 인구가 5억8천만 명에 이르렀으며, 2020년까지는 10억 명을 돌파할 것이라고 한다. 이는 같은 기간동안에 전세계적으로 예상되는 인구 증가율이 50％ 미만인 것에 비해 훨씬 높은 75％의 증가로서 전례가 없는 일이며, 모든 정책 입안자들의 즉각적인 주의가 요구되는 문제이다. 한편 우리 나라도 예외일 수 없어, 통계청의 인구추계 자료에 의하면 1969년 948.5 천명으로 3.0％에 불과했던 우리 나라의 65세 이상 고령 인구는 2000년 현재 3,395천명으로 전체 인구의 7.2％에 달했으며, 2019년에는 전체 인구의 14.4％에 까지 이르러 고령사회(aged society)로의 진입이 예상되고 있다.

본 연구에서는 글이해시의 참조관계 처리과정에서 맥락이 어떤 역할을 하며 다른 통사단서와는 어떤 관계를 갖는지를 대명사 해결을 중심으로 조사했다. 실험 1에서는 대용어 문장의 국소적 맥락에 의한 촉진효과가 관찰되었다. 그러나 맥락과 통사단서간의 상호작용으로 맥락 촉진효과는 통사적 명료조건에서보다는 애매조건에서 더 강하게 나타났다. 실험 2에서는 국소적 맥락정보가 없더라도 선행글의 전체주제적 맥락정보가 촉진제 역할을 하는 것으로 밝혀졌다. 또한 전체주의적 맥락이 주어지는 경우 글의 표면구조적 특성에 따른 위치효과가 나타나지 않았다. 즉 두 개의 실험을 통해 대명사 해결에 미치는 통사단서의 효과가 일부 지지되었으며, 특히 맥락효과는 국소적, 총체적 수준에서 모두 일관되게 입증되었다.

This study was carried out to compare quality characteristics and physiological activities of Korean traditional wines fermented by addition of puffed sorghum powder. Using a two-step brewing process for fermented wines, pH, acidity, ethanol, color, tannin, ${\alpha}-glucosidase$ activities, antioxidant, and reducing sugar levels as well as sensory evaluation were measured during fermentation at 2-day intervals until day 8. The pH levels of fermented wines ranged from 4.07 to 5.53, and acidity ranged from 0.13 to 0.86. On the last day of fermentation, alcohol contents of control, raw sorghum, steamed sorghum, and 25, 50%, and 100% puffed sorghum were 16.8%, 11.7%, 13.4%, 16.5%, 15.2%, and 16.4%, respectively. The reducing sugar and ${\alpha}-glucosidase$ activities of puffed sorghum fermented wines were relatively higher than those of the control group, whereas those of steamed sorghum were lowest. As puffed sorghum powder content increased, antioxidant activity significantly increased. In the results of the sensory evaluation, overall preference of 50% puffed sorghum fermented wines was highest among the samples. The results of this study show that physiological activity and quality characteristics of fermented wines containing puffed sorghum powder contribute to value added improvement of sorghum processing.

Effects of clarification and aging of honey wine(mead) and fruit honey wine(melomel) were investigated. Among the clarifiers tested, 'kaki shibu' and 'sake light' were effective in clearing honey wine. Clear honey wine with more than 90% light transmittance was obtained by treatment with $0.05{\sim}0.1%$ of 'kaki shibu' and 'sake light' for 2 days. Higher concentration of these clarifying agents was needed for the clarification of fruit honey wines. Treatment with 0.5% of 'sake light' and $0.05{\sim}0.1%$ of 'kaki shibu' for 4 days was effective for clearing Tangerine honey wine and Japanese apricot honey wine. Though Hunter L-values of honey wines decreased a little bit by using clarifiers, their light transmittance became more than 98% after ultrafiltration. As the content of soluble solid in mash at the beginning of fermentation increased, the content of acetaldehyde, n-propyl alcohol, n-butyl alcohol and iso-amyl alcohol of honey wine increased during aging, while the content of iso-propyl alcohol decreased. During the aging of honey wines, the sensory quality of them became milder as the amount of acetaldehyde and fusel oil decreased. Among more than twenty different volatile flavor components detected from honey wines, 1-phenyl ethyl alcohol, benzyl alcohol, 2-phenyl ethyl alcohol, octacosane and triacotane were identified as the major components for the flavor of honey wines. Sensory evaluation of the honey wines indicated that the melomel made with Japanese apricot was better than the Tangerine melomel in the aspects of taste, flavor, color and the overall acceptability. Tangerine melomel was even inferior to honey wine(mead).

Addicts pay more attention to addiction-related cues, such as substance or behavior. And increased attention to these cues is associated with craving. Methamphetamine is the most abused drug among domestic drug offenders, with continually increasing rates of recidivism. Of the total number of reported drug offenders in the last three years, 21.1 percent have been women. Even so, research on female drug offenders is inadequate, rendering policies and fundamental data for the development of psychotherapy programs insufficient. The present study intended to investigate whether female methamphetamine addicts displayed an attention bias towards drug cues. A dot probe task was conducted on 22 female methamphetamine addicts (addiction group) and 22 non-addicts (control group). The task allowed the correct response rates and correct reaction times of the participants to be calculated according to the positioning of the drug and neutral cues. The analysis results revealed that the control group displayed no difference in correct reaction rates and correct reaction times between the drug or neutral cues. While, the addiction group showed lower correct response rate and slower response time for drug cues in comparison to neutral cues. The results of this study are significant in that it identified the attention bias characteristics toward drug cues of female methamphetamine addicts who were disconnected from drugs.

This study is to examine closely the frame structure of buildings in the royal palace of Josen dynasty, focused on inner buildings of Changgyeonggung(昌慶宮) which is built in 19th century, through considering the member size of main structure and analyzing the slope of a rafter. The plans of a size on main member are as follows ; firstly, a length of the perimeter column was accorded with Gunggwolji(宮闕誌) and the planning size of interior column was shown to a Chon(a Korean inch, 寸) unit. The slope of long common rafter that is formed between the perimeter and interior columns was grasped with limits of a definite value. This is that the perimeter column is trimmed to a Chon unit, as Yeongchunheon(迎春軒), In the roof frame of Korean traditional timber architecture, the slope of rafter, first of all, is to decide the slope of long common rafter and then to decide a height of ridge piece settled whole height of a building. And it is regulated with position and height of a post so as to set up middle rafter. Especially, the slope of long common rafter, it is not to be decide through scale of a building but through a length of the perimeter column and composition of bracket structure. And in case middle rafter, the process of its slope is to devide the central bay on the side of a building into equality, and then to adjust position and length of a post.

In April, 1995, ANC government was established in South Africa. The Black government set up Truth and Reconciliation Committee in November, 1995. The Committee investigated approximately 50,000 cases for 3years. Through this process, Black and White in SA could be united into one. Finally, the system of racial discrimination, lasting for about 300 years, was abolished. The Committee played a role as a social infra-structure, which was to perform and solidify democracy in SA. Reconciliation, agreement, Participation, equality, Communication, and Reformation of law system were practically implemented by the Committee. Many people evaluate TRC's activity, which had the reformative and democratic character of the object of investigation, investigative criterion, investigative process, and the approval of investigative result. But De Klerk evaluates that TRC retaliated the White with legal. J. Cronin evaluates that TRC transiently change democracy of the South Africa, and many other social movement groups had a negative view about TRC. But the Black and White in South Africa transformed 'discriminated society' into 'united one'. The Committee took the initiative in such a change. The Committee was not an organization needed for the policy, but the committee was the policy itself to change the former society to the new one. Now The ANC government was forwarding TRC's roles and functions to the truth and reconciliation bureau of the Justice Department for further action. The ANC government has to execute some policy for social reconciliation. Firstly, the government needs to build construction social and national system for making close investigation into the White's historical guilt. Secondly, it must be executed to TRC's recommendation pursuit social reform of social infra-structure in the South Africa. Thirdly, The government should execute policy for the Black's right as labors and social member. Lastly, the government must investigate still-remaining historic state violence and infringement of human right for social reconciliation.

This study was conducted for technology development and industrial and enterprise system design for the sustainable life of mankind. Human society is facing a crisis. As the power of mankind has increased due to the development of nuclear weapons and information and communication technologies, the risk of human society has greatly increased. The value of growth and freedom is increasing due to capitalism and democratic systems, so technological innovation is accelerating, and industries and companies are growing significantly. New technologies and industries can greatly develop human society and put it at risk. This study was conducted with the aim of redesigning technology, industry, and enterprise systems so that humans who live on Earth can be more sustainable for a longer time. It presented a practical alternative for a long-term sustainable human society. It suggested alternatives for what philosophy and methodology should be developed for the whole of humanity and in each individual national society, for developing technologies, fostering industries, and operating corporate systems. First of all, the problems of the technology development system, industrial system, and enterprise system of human society were analyzed. The characteristics and problems were analyzed in terms of sustainability of human society. The necessary and sufficient conditions for an alternative system to solve the raised problems were derived. A system that satisfies these conditions was designed and presented. The alternative system was named as a servicism system as a system based on the service philosophy. The structure, operation model, and implementation plan of the new technology industry enterprise system were presented. In the future, follow-up studies are needed to be concreted at the level of individual countries and human society as a whole.
